So now my 3x Solar panels got here today, and I was eager to test them out, and see if I could use them with the boost converter. Tested the output voltage of each solar panel, and they were outputting 3.8vdc using 23watt CFL Lamps (5,300 kalvin Temp Color "daylight")..

They are rated for 4.5Vdc @ 1.5 watt @ 0.334 Amps output. I have the spec sheets that came inside each package, and that's what the exact specs are. (2770051) Is they're names.

WHY ARE THEY OUTPUTTING ONLY 2.081 Volts DC, at only freaking 0.003 Amps (3,184 uA) ?

I don't understand what I'm doing wrong.. Hooked up this way, the two that are in Series on the right output about 7.2 volts DC, and then on the left, I have one of em hooked up to the other two panels in parallel.

They are only measuring the current & voltage going into the Boost Converter.. Only reads 2.0 volts, and only 0.003 Amps. I really don't understand what I'm doing wrong.

Can someone please help or try to shine a little light on what I might be doing wrong? Please..? I'd really appreciate it. I've measured the current the correct way. I hooked the Red Test lead to the Red (Possitive) of the Solar Panel Positive output, and I hooked the Black Test Lead to the Red INPUT of the source where the positive connection is going to. So basically testing the current inline with the positive in & out.

I've also tested the boost convert the same way when I tested how much current was being drawn when I tested the USB Connection on the Laptop & XBOX360 Charging Dock.

Now I want to use these solar panels, to charge my Samsung Galaxy S3 phone without batteries..

Here's what I got..

Tested each panel, and still the same.. 2.082 Volts, WTF is going on..? Why do they drop so low..? I also tested the current the combined solar panels output current, and it doesn't matter if I test them combined before the diode or anything, still 0.003A @ 2.082 Volts..

No it does not matter.The problem is that they are rated at maximum power produced in perfect conditions but in reality they produce power accordingly to how powerful light is that day.You will probably get 30% less power.

Tested it out today, turns out today was a clear day. Barely any clouds in the sky. 260 - 300+ mA @ 5.0+ volts. Used the boost converter at first, then used just the solar panels to charge the phone a little bit.

It's kinda odd.. These panels say they're rated for 4.5v @ 334mA but when I joined them all up, only gave me 300mA @ 5v. I don't know why. Was getting some nice sun too.

Geesh, that $400 Panasonic Lumix LX7 sure makes things look different. Kinda dusty.. But when you look at it in person, doesn't look half as bad as it does in the photo.

Just using the three solar panels in parallel, No Boost Converter. RadioShack 1.5 Watt - 4.5v - 0.334A Solar Panels.

Yes I'm aware of the shadding effect on Solar panels, but even with the sun hitting them evenly, without any shading or partial shading, didn't get more than 300+ mA.
